Life History and Behaviour of the Leafhopper Macropsis fuscula (Zett.) (Homoptera: Cicadellidae) in British Columbia1
Published online by Cambridge University Press: 31 May 2012
Extract
Macropsis fuscula (Zett.), which is a species common in Europe, was first reported in North America in 1952 when specimens were collected from loganberry on Lulu Island, British Columbia. High infestations persisted on Lulu Island until the destruction of most of the loganberry canes there during a severe freeze in November, 1955. New cane grourth was normal in 1956, hot no leaf-hoppers could be found. Only a few nymphs were found in 1957, but there was an average of 14 nymphs per 100 fruit buds in 1958, and 48 nvmphs in 1959, compared to 32 nymphs during the last season of high infestations in 1955. Re-infestation from hardy wild hosts common in the area probably largely accounts for the rapid re-establishment of this pest on cultivated loganberry.
